FIELD OF THE INVENTION

BACKGROUND OF THE INVENTION

The Complementary Metal Oxide Semiconductor (COMS) element is constructed with the P-channel Metal Oxide Semiconductor (PMOS) and the N-channel Metal Oxide Semiconductor (NMOS), together. The CMOS element is the most fundamental circuit structure of the driving chip in the liquid crystal display. In traditional LCD, the driving chip and the substrate (such as the glass substrate) are separately designed without integration, which makes the manufacture cost of the LCD is higher and the thin and light design is hard to be real. In case that the driving chip can be directly manufactured on the substrate, it will be a huge progress for the display devices, such as LCDs. At present, the Low Temperature Poly-silicon (LTPS) technology is generally employed to manufacture the CMOS element on the substrate, which has certain progress in comparison with the separate design of the driving chip and the substrate. However, the LTPS technology is to respectively manufacture the semiconductor layers of the PMOS and the NMOS in the CMOS element. The relatively complicated manufacturing processes such as the laser annealing, doping, and ion implantation are included, and thus the cost is higher.

It should be understood that in another embodiment, the first type metal oxide semiconductor layer 140 is a P-type metal oxide semiconductor layer, and the second type organic semiconductor layer 160 is a N-type organic semiconductor layer. As the first type metal oxide semiconductor layer 140 is the N-type metal oxide semiconductor layer, the first type metal oxide semiconductor layer 140 is Indium Gallium Zinc Oxide (IGZO) or Indium Tin Zinc Oxide (ITZO).

The introduction is conducted that the first type metal oxide semiconductor layer 140 is a N-type metal oxide semiconductor layer, and the second type organic semiconductor layer 160 is a P-type organic semiconductor layer. Then, which comprises the first type metal oxide semiconductor layer 140 is a N-channel Metal Oxide Semiconductor (NMOS), and which comprises the second type organic semiconductor layer 160 is a P-channel Metal Oxide Semiconductor (PMOS). Namely, in FIG. 3, the NMOS is at the left side of the dot line, and the PMOS is at the right side of the dot line. The first metal layer 120 is the gate of the NMOS, and the insulation layer 130 on the first metal layer 120 is the gate isolation layer of the NMOS, and the first metal part 151 is the source of the NMOS, and the second metal part 152 at the left side of the dot line is the drain of the NMOS.

Both the first etching stopper layer 191 and the second etching stopper layer 192 are employed to protect the first type metal oxide semiconductor layer 140 so that the influence of the dry etching process to the first type metal oxide semiconductor layer 140 in the procedure of forming the second type organic semiconductor layer 160 can be prevented.

It is understood that in one embodiment, the CMOS element 1 only comprises the first etching stopper layer 191 without the second etching stopper layer 192; or in another embodiment, the CMOS element 1 only comprises the second etching stopper layer 192 without the first etching stopper layer 191. As the CMOS element 1 comprises one etching stopper layer (the first etching stopper layer 191 or the second etching stopper layer 192), it still can protect the first type metal oxide semiconductor layer 140 in comparison with the CMOS element without the etching stopper layer so that the influence of the dry etching process to the first type metal oxide semiconductor layer 140 in the procedure of forming the second type organic semiconductor layer 160 can be prevented; as the CMOS element 1 comprises the first etching stopper layer 191 and the second etching stopper layer 192 at the same time, it can better protect the first type metal oxide semiconductor layer 140 so that the influence of the dry etching process to the first type metal oxide semiconductor layer 140 in the procedure of forming the second type organic semiconductor layer 160 can be prevented. Preferably, as the CMOS element 1 comprises the first etching stopper layer 191 and the second etching stopper layer 192 at the same time, the first etching stopper layer 191 and the second etching stopper layer 192 are at the same layer for convenience of forming the first etching stopper layer 191 and the second etching stopper layer 192.
